What theory did Alfred Wegener suggest about tectonic plates and what evidence did he have?
He is most notable for his theory of continental drift, proposed in 1912, which hypothesized that the continents were slowly drifting around the Earth. However, Wegener was unable to demonstrate a mechanism for continental drift, which, combined with his mostly circumstantial evidence, meant that his hypothesis was not accepted until the1950s, when numerous discoveries provided evidence of continental drift… Alfred Wegener was a meteorologist and an astronomer. As a non-geologist, Wegener’s trespass into the discipline was not welcomed. In January 6th 1912, he delivered an address to the Geological Association in Frankfurt, entitled “The Formation of the Major Features of the Earth’s Crust (Continents and Oceans)”… The missing “mechanism was supplied with the development in the 1960s of the theory of Plate Tectonics, which is a scientific theory describing the large scale motions of Earth’s lithosphere.
